' Specification of Letters Patent.

Application filed April 16, 1915. Serial No. 21,741.

To all whom it may concern Be it known that I, STEPHEN 0. DE ORLOW, acitizen of the United States, residing at Akron, in the'county of Summitand State of Ohio, have invented a new and useful F an, of which thefollowing is a specification.

The device forming the subject matter of this application is a hand fanadapted to be employed by bootblacks and others for creating a forceddraft.

One object of the invention is to provide novel means for imparting amovement to the member which carries the fan blades.

Another object of the invention is to providenovel means whereby at thewill of an operator, the fan blades may be held in anoperative,'laterally projecting position, or in a folded position.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

IVith the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed an d claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can, be made within thescope of what is claimed, without departing from the spirit oftheinvention.

In the accompanying drawing: Figure 1 shows the invention inlongitudinal section, parts appearing in elevation; Fig. 2 is a crosssection on the line 2-2 of Fig. 1; Fig. 3 is an end elevation, whereinsundry parts have been sectioned, the line l1 on Fig. 3 indicating thecutting plane on which Fig. 1 is taken; Fig. 4 is, a cross section onthe line 4-4 of Fig. 1. i

In carrying out the present invention there is provided a supportdenoted generally by the numeral 1. The support 1 may be, of variousconstructions, but in the present instance it is a composite structure,

comprising a thimble 2 having laterally prov jecting finger pieces 3, atube 4 threaded or The invention includes aislide 6 in the form of atube mounted to reciprocate on the guide tube 5, the slide 6 beingprovided at one end with a head 7. In operation, the fingers of theoperator are engaged with the elements 3, the palm of the hand of theoperator engaging the head 7 to advance the slide 6 on the guide tube 5,for a purpose Patented Nov. 21, 1916. r

e 6 1s. a compresslon sprlng 9, one end of end of which engages the'head 7. The

which engages the abutment ring 8, the other spring 9 preferably is ofhelical form, and 1 into the abutment ring 8, but slides freely therein.I

The invention comprises a tubular primary clutch 14 with which thethreaded portion 12 of the shaft 10 is engaged, the primary clutch attimes being engaged with the abutment ring 8. Projecting from the shaft7 10 and located between the threaded ribs thereof is a projection inthe form ofa pin- 16 which coacts with the clutch 14 in a manner to bedescribed hereinafter.

Secured in the outer end of the tube 4 is an abutment rin 17 andjournaled in the abutment ring 1 is a secondary tubular clutch 18provided at one end with teeth 19:

adapted to cooperate with the teeth 15 of the primary clutch 14.

17 to prevent outward movement of the clutch, the clutch being providedwith an outer shoulder 30 and terminating in a tubular, externallythreaded stem 22.

Surrounding the stem 22 of'the secondary clutch 14 is a carrying member23 in the form of a. ring, the same abutting against The secondary"clutch 18 is equipped with an annular, inner shoulder 20 coactingwiththe abutment ring the shoulder 30 on the clutch 18. The carrying ring 23may be provided as shown in Fig. 2 with radial ears 24 disposed inpairs, brackets 25 being pivoted between the ears 24 of each pair, thebrackets being secured respectively to blades 26. 'Any other suitablemeans may be provided for pivotally connecting the blades ,26 with thecarrying member or ring 23 and since the blades may be of any desiredform, a detailed descripwill not be so inflexible as to inflict injury,should they come in contact with garments of a person, or with an objectof any sort.

The blades 26, it is to be noted, are pivotally assembled with thecarrying member 23 intermediate their ends, the inner ends of the-bladeslbeing bifurcated to form fingers 27 lying on opposite sides of thestem" 22 of the clutch 18.

Threaded onto the stein 22 is a nut 28 which may be described as atubular A member adapted to engage the fingers 27 of the blades 26, tobind the same together and to hold the fingers of one blade engaged withthe abutment ring 23 25 the blades thus being held in the outstand ingpositions shown in solid line in Fig. 1. At this point it may profitablybe observed that when the occasion for the use of the structure haspassed the nut 28 may be backed off the fingers 27, the blades 26 beingfolded into the dottedline positions of Fig. 1, the blades then lying inapproximate parallelism with the support 1. The nut 28 may then beadvanced on the stem 22 and, as shown at 29, the nut will engage withthe fingers 27 of the blades and hold the blades in parallelism to thesupport 1 as above mentioned.

tion of the arrow A by the pressure of the palm of the hand of theoperator against the head 7. During this operation, the spring 9 is putunder compression, the same being engaged at one end by the head 7 andat the other end by the abutment ring 8. When the slide tube 6 isadvanced inthe direction of the arrow A, the threaded shaft 10 iscarried with it, the shaft moving freely through the abutment ring 8.The first function of the shaft 10 as it is advanced is to advance theprimary clutch 14' until theteeth 15 thereof coact with the teeth 19 ofthe secondary clutch 18. Thereafter, the threaded shaft 10 cooperateswith theprimary clutch, to rotate the same, the shaft moving freelythrough the secondary clutch 18 and through the tubular stem portion 22of thewsecondary clutch. When the primary clutch 14 is rotated, thesecondary clutch 18 will be rotated, carrying with it the ring 23 andthe blades 26 which are held to the 2 ring 23 by the action of the nut28, the ring 23 being bound against the shoulder 30 on isclaimed is Inpractical operation, the fingers of'the operator are engaged with. theelements 3 and the slide tube 6 is moved in the directhe, secondaryclutch., When pressure on the -slide tube 6 is released, the blades 26and the secondary clutch 18 will continue to rotate by inertia for atime, the spring 9' reacting to draw the primary clutch 14 out ofengagement with the secondary clutch--18, the projection 16 coactingwith the primary clutch-'14 to'retract the same under the action of thespring 9, it being noted at this point, that the projection, coactingwith the primary clutch 14 when the latter is in engagementwith theabutment ring 8, limits the movement of the slide tube 6 in thedirection of the arrow B under the action of the spring 9.

Having thus described the invention, what '11.
